Non-volatile resistive switching in the dielectric superconductor YBa 2Cu3O7-δ

We report on the reversible, non-volatile and polarity-dependent resistive switching between superconductor and insulator states at the interfaces of an Au/YBa2Cu3O7-δ (YBCO)/Au system. We show that, upon application of electric pulses, the superconducting state of YBCO in regions near the electrode...

We show that, upon application of electric pulses, the superconducting state of YBCO in regions near the electrodes can be reversibly removed and restored. In addition, four-wire measurements reveal that pulsing also induces significant non-volatile changes in the bulk resistance. We argue that our observations are compatible with a scenario where the switching effect is due to migration of oxygen ions along grain boundaries that control the inter-grain superconducting coupling. © 2009 IOP Publishing Ltd.
